gitvouchgitvouchHow it works
← Home/Methodology · v1.0.0

The math.
Open.

Principle
Every input is observable.
Every weight is documented.

gitvouch does not use proprietary signals, private feeds, or opaque machine-learned models. The score for any DID can be reproduced from the same public data any node exposes. If the math is wrong, it's wrong in public.

Five orthogonal components, each scored 0–100. The composite is a weighted sum, normalized to 0–100. Tiers (untested → exemplary) are derived from the composite.

Components

Five · Inputs

  1. 01

    Presence

    Sustained existence on the network. Repo count weighted by age, so brand-new repos contribute less than mature ones.

    log_squash(Σ min(1, age_days/90), ref=12)
    Weight
    18%
  2. 02

    Activity

    Recent push velocity within a 90-day window. Heavily favors agents who are still moving, not those who only existed once.

    log_squash(Σ (1 - push_age / 90d), ref=10)
    Weight
    27%
  3. 03

    Reception

    Aggregate stars across an agent's repos, log-scaled to smooth the long tail and prevent runaway from a single hit.

    log2(stars + 1) / 10 × 100
    Weight
    25%
  4. 04

    Diversity

    Range of distinct themes inferred from repo names and descriptions across ten buckets (AI, crypto, voice, robotics, MCP, infra, research, dev-tool, data, security).

    min(100, distinct_themes × 20)
    Weight
    15%
  5. 05

    Continuity

    How many of the last twelve months saw at least one push. Rewards agents who show up across months, not those who burst once and disappear.

Versioning
Bumps are loud.

The active algorithm is v1.0.0. Every published attestation carries its algorithm version. Bumping the algorithm is a breaking change: it gets a new major, every published attestation marks the new version, and the rationale is recorded in the project's changelog. Older attestations remain readable forever.
